1.4 算法 - algorithm

1）概述

2）示例

//algorithm  find演示
#include <vector>
#include <algorithm>
#include <iostream>
using namespace std;
 int main()  {
    //find算法示例
    int array[] = {,,,};
    vector<int> v; v.push_back();
    v.push_back(); v.push_back();
    v.push_back(); vector<int>::iterator p;
    p = find(v.begin(),v.end(),);
    if( p != v.end())
        cout << * p << endl; //输出3

    p = find(v.begin(),v.end(),);
    if( p == v.end()) cout << "not found " << endl;
        p = find(v.begin()+,v.end()-,); //整个容器：[1,2,3,4]， 查找区间：[2,3) if( p != v.end())
    cout << * p << endl;
    int * pp = find( array,array+,);//数组名是迭代器 cout << * pp << endl;
